Abstract: A copper-containing catalyst of the composition of N2O contains a compound of the formula MxAl2O4, where M is Cu or a mixture of Cu and Zn and/or Mg and x is from 0.8 to 1.5. The novel catalyst is used in a process for the catalytic decomposition of pure N2O or N2O contained in gas mixtures, at elevated temperatures.

Abstract: The catalyst is in tablet form having a diameter of 0.8-5 mm and a height of 0.8-5 mm. The catalyst is prepared by: (a) precipitating a solution of zinc and aluminium salts (Zn:Al ratio is 3-1:1-3) with and alkali carbonate or hydroxide solution at a pH of 5-12 and a temperature of 20-100 degrees C; (b) removing and washing the precipitate to remove alkali ions; (c) drying the precipitate; (d) calcining the precipitate at 250-800 degrees C to a mixed oxide; (e) dispersing the mixed oxide in an acid solution of copper and zinc salts (Cu:Zn ratio is 1-20:5-1); (f) precipitating the dispersion with an alkali carbonate or hydroxide solution at a pH of 6-9 and a temperature of 20-100 degrees C; and (g) repeating steps (b) to (d). The solutions in steps (a) and/or (e) additionally contain oxides of platinum group metals, groups 5, 11 and the lanthanides.
